GEORGE K. BROW'N, ()l MOULTUNBORO, NEW HAMPSHIRE.

Specification of Letters Patent No. 18.433, dated October 20, 18-57.

To all whom. it may concern Be it known that. I. Gnonon K. BROWN. ofMoultonboro. in the county of Carroll and State of New Hampshire. haveinvented a new and Improved Machine for Husking Corn; and I do herebydeclare that the following is a. full. and exact description there-- of.reference being had tothc accompanying drawings, making part of thisspecification, Figure 1 being a plan of the machine; Fig. 2. a sideelevation thereof; Fig. 3. a front elevation of the same; Fig. l. alongitudinal vertical section in the plane indicated by the line on m,Fig. 3.

Like letters designate corresponding parts in all the figures.

I employ a drum. or wheel. I). of convenient diameter. and of athickness sufficient to receive the full length of any car of corn to hehuskcd. This drum is secured to a driving shaft B. which is mounted in asuitable frame A. and driven by a winch. or by power communicated to apulley C. on one end thereof. The drum. thus caused to turn at asuitable rate of speed. serves to reccive the cars of corn. to conveythem through the machine. and hold them to be subjected to the requiredoperation of husking. as hereinafter set forth.

At suitable distances apart. holding sockets L. L. are formed in.'orsecured. on. the periphery of the drum. substantially of the form andarrangement shown in the drawings. The hollows Z. Z. thereof. in whichthe cars of corn are placed. have low sloping sides. or scarcely any infront; but. behind. the sides are higher and more abrupt. substantiallyas shown in Fig. 4; or such that the ears of corn will be allowed toturn in the hollows. in the act of having their husks stripped oil". andnot be allowed to pass over said rear sides or backs; and at the sametime. so that said backs shall not come in contact with the strippingteeth presently to be described. Hence. said backs should be low enoughto allow the stripping teeth to remove all the husks from the smallestears of corn; and high enough to hold the largest ears of corn. Thesockets may project some what from the periphery of the drum. asrepresented.

At one end of each socket: L. is secured a gage plate I. to the face ofthe drum. substantially as shown; or the several plates may compose asingle rim occupying the entire circle. The projecting edges of these lgage plates correspond somewhat in shape with the profiles of thesockets; but project considerably farther than the said sockets, or atleast in the hollow portions 1'. i. correspondiug with. or opposite to,the hollows I. 7-. ofthe sockets. In the said; hollows of the plates.rest the stems of the ears of corn: and against their projecting sides.the butts of the ears are placed. when placing the cars in the sockets;and thus the'ears are all roperly gage/cl in position for beingsubjected to the knife which cuts off the stems. and ends of the husks.They may he. adjustable to different distances from th ends of thesockets.

he knif H. which cuts oil the stems. and ends of the. husks. is secured.at the rear end, to a standard a. or its equivalent, projecting fr m theframe A; and the front end is secured on a pin. or rod, d. the bearingsof which rest in sliding blocks f. f. held down by springs y. Thus thefront end of the knife is allowed to yield when necessary. Its situationis such that the motion of the cars beneath it will produce a drawing orwcdging out upon the stems thereof. as indicated in Figs. 2. and 4. Theedge of the knife is situated between the gage plates I. I. and the endsof the sockets L. L; and may he in close proximity to. or contact with.said gage plates; and by making the edges of the gage plates sharp. theywill serve to assist in cutting off the stems, they and the knife actingtogether like shears. Instead of giving sharp edges to the gage plates.they may have sharp teeth. or serrated edges. so as not only to assistin cutting the stems of the ears. but also more surely to seize. andhold the ears in place.

Above the drum. and at a suitable distance therefrom. is situated a setof curved ribs E. E. arranged substantially as represented in thedrawings. Their front or upper ends are mounted on the yielding rod (2'.above described. or its equivalent. so that they can yield. or be raisedsomewhat when necessary. lVhen guides j, j. projecting downward from theframe A. are employed to keep the ribs E. E, in their proper places.they should be provided with slots in which the rod (1. may move as muchas required. The lower ends of the ribs rest upon a bar of the frame.and are kept in proper position by guide pins I). Z. as shown; so thatthe ribs have narrow siaces between one another. The Illo held down witha proper degree of force, by springs G. (l, which are arrangedsubstantially as represented. In the under. concave sides of these ribs,coinlneneing just behind the cutting knife I, and

extending some distance back, are inserted ribs enables them to adaptthemselves to any size of ears of corn. Below the teeth are inserted inthe ribs. brushes u, a, which serve to brush otl' any remaining huskswhich may cling between the rows of grain, and also to remove the silkstherefrom.

Between the holding sockets L, L, slender teeth or pins it. ii. areinserted into the periphery of the drum D. so that they will passthrough the spaces between the ribs G, G. These teeth serve to clearaway all hue s which may gather between the teeth in, m, and brushes a,)1. as fast as they collect. All the husks and impurities may be removedfrom the machine by means of a blast of air created by a revolving fanM, and di reeted beneath the falling husks. by a spout N. The motion maybe communicated to the fan, by a. band 72, passing from a. pulley l. onthe driving shaft B, to a pulley Q, on the axis ll, of said fan.

I do not claim hollows or sockets, for holding the ears of corn, for thepurpose of being conveyed into the machine; nor do T claim a. stationaryknife in connection with a feeding drum for cutting otl' the stems I yand husks; but these stripping teeth. The elasticity of the What I claimas my invention and desire to secure by Letters Patent, is-

The rotating drum 1), provided with holding rackets L. gage plates .l.and clearing teeth la, and acting in combination with the stationarycutting knife H. and elastic ribs E. provided with stripping teeth in,with or without brushes 12 on their under sides. in

l the manner and for the purposes specified.

In witness that the above is a true specification of my improved machinefor husking corn. l'hereunto set by hand this twentyninth day of May,1857.
